Bunker, or Scientists Underground (2006)

Original title: Бункер, или Учёные под землей

In the year 2012 (a future time when the film was made), an underground laboratory ten kilometres beneath the steppes of Western Siberia is the stage for the top-secret Project BUNKER. Distinguished scientists have been working on a mysterious scientific experiment for the last three years, with a strange, anonymous, and extremely popular erotic manuscript circulating through the complex serving as their only distraction. Now a new researcher has arrived — a veterinarian, despite the lack of animals at the facility — and the scientists already in place are wondering why.
